Apple has released iMovie ’11 9.0.9, a small update for the video editing app that is nearing its third birthday (the iLife ’11 suite was originally released on 20 October 2010). This update squashes a bug that prevented iMovie from recognizing video cameras connected to your Mac and improves compatibility with projects that are imported from iMovie for iOS. Finally, it also includes unspecified stability improvements. ($14.99 new from the Mac App Store, free update through Software Update or the App Store app, 1.08 GB)
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
